Overview

Upgrade. Add more light output and a modern appearance to your backup lights with the 921 XPR backup bulb. Each of the four sides of this bulb is populated with 4 high power LED chips for maximum brightness. Housed in an aluminum casing with a textured finish for superior heatsinking properties, the XPR will last for years to come. Best of all, installation only takes minutes - simply take out your factory bulb and the XPR will fit snugly in the socket.

Brightness. At 720 lumens, the XPR will provide significantly more light output than your factory bulb. All Diode Dynamics LED lighting is rated with accurate, measured lumen figures, not calculations or guesses. We test the true output in-house, and provide you the real numbers to compare.
